Climb up the stairs lying between fountains move to the higher level of the courtyard. Turn right near the well, go up the next stairs to the terrace. Move to the right from the stone table, enter the narrow pass limited by balustrades. At its end you will find the casket with 10 sand credits. Return to the stone table now and to the left this time. Stick into analogous narrow pass. At its end you will find the decorative tile in the wall. Run vertically on the wall and stamp on the tile, and the door will open below, by the well.
Run to the newly opened door and enter it, you will be inside the tower. Go straight ahead over the corridor, and then to the right. Turn at its end to the left, jump over the rail and hang from its other side. Jump over the precipice landing on the other rail over the opposite side. Jump onto the terrace then turn to the right. Localize delicate outline of the door in the wall and hit it with all power. Go through the smashed entrance, run down the stairs. You will enter the blank chamber which will turn out to be the lift platform. You will go upwards to the terrace.
You are located at top level of the tower. The Vizier is showing up, you see captured Farah also. The girl isn't losing her self-assurance and despite the mirthless situation she isn't yielding villain flirtation. The spat Vizier got angry and he want vent it on you. You are facing each other. The enemy attacks you on and off, off and on with single blows, strong enough to strike you down. When you go away from him, he is flinging magic bullets at you.
The best method to stiff the Vizier is to jump when he is inflicting the blow, and then firing up quick combo which will reduce the his energy bar considerably. The boss is stopping after every attack for the moment, so attack him then. The Vizier's attacks are strong, but schematic and therefore you will sense moments when you have to jump. After inflicting the series of blows retreat and wait until he will approach again to hit.
The vizier is flying upwards three times during the first phase of the skirmish in order to strike you with pieces of columns. You may avoid his attacks escaping backwards and rolling over the floor when bullets are close by. Sands of Time Powers may help you also, especially Eye of Storm but I am not recommending losing the sand at this quite easy stage. It will be useful later. After taking around the 1/3 of energy bar the fight will change.
Irritated Vizier will crush walls around the arena of the fight, and will scatter pieces of columns and walls over the terrace. They are circling round the whole square now making the deathly risk to you. You have to avoid them and to weave through them because every contact with the piece of the wall ends with serious wounds. It is most safely in very center of the arena and most outside, near the rail enclosing the terrace. At this stage your fight against the vizier looks completely different than previous. The boss is raised a few meters above the ground and from time to time is flinging magic bullets at you.
In order to whip Vizier's hide, run fast in his direction, avoiding circling obstacles. Run vertically on the column behind the boss and push (not releasing the direction key) the button initiating the speed kill ("E"). If you do it correctly you will take off to the enemy's direction and you will have a chance to hurt him with triple speed kill. Hit when the dagger shines at your hand. If you are late, the vizier will knock you down to the earth and you will have to construct the attack from the beginning..
In order to be a success you have to jump to the boss' neck three times inflicting him three blows with speed kill each time. It isn't easy, because every successful attack increases the Vizier's vigilance and speed. The hardest moment is at the third attempt to jumping on his back. The enemy is moving from pole to pole so fast that you aren't able to catch him. Use the eye of Storm in order to slow down his movements for the moment. After conducting three successful attacks (he loose his wings) you will force the Vizier to the escape.
Don't be so pleased because it isn't still the end of the fight. Your enemy naturally has evacuated but he didn't escape from the arena, only flew upwards. Located high above the battlefield he raised in the air all pieces of walls. Is it wise? Probably not, because blocks thrown away in the air and rocky shelves arranged the kind of path which will lead you to the boss.
Before you will enter the "war path" remember don't' let the Vizier knock you down from platforms (particularly from horizontal bars) with vizier's bullets. If you haven't wasted sands of the time earlier, you are now able to protect yourself with Sands of Time Powers. Slow down the time before every more complex movement and when the boss' bullet will reach you and you will fall down the platform, rescue yourself with Recall. The way leading to the boss is described below. Let's go to work!
Come up to the column, where the piece of the wall is hanging not high above. Run vertically on the column and take off backwards, reaching the brink of the block behind your back. Clamber up it, then jump to the next block straight ahead, also climb it. Turn to the left and jump to the horizontal bar. Stand on it, turn around to the other side, and then jump to the block put higher right ahead. Clamber up it, turn to the left. Take off straight ahead and reach the brink of the vertical dyke. Jump from it to the horizontal bar to the front, stand on it and jump right ahead to the horizontal platform.
Turn to the right and jump to the next platform, the take off diagonally to the next vertical dyke. Clamber up it, take off forward to the platform, and then jump to the horizontal bar right. Swing yourself and jump forward and you will reach the shelf. Run vertically on the wall close by and take off backwards reaching the brink of the platform above you. Jump to the last platform, move over it till the end to the left then jump to the Vizier, pushing the button initiating speed kill. The final action will begin, during which watch your dagger vigilantly. When it flashes - push the attack key.
It is the vizier's decisive end. Your enemy will be annihilated and also his whole dark army. You will feel after a while that the curse loses the power above you and the Dark Prince's spirit is leaving you. You will feel free. Farah will also be freed from sandy ties. The Kaileena's spirit will appear in order to take the dagger of the time. You will notice the royal crown on the floor. When you reach for it somebody will beat you. You raise your eyes... The Dark Prince has returned!
